<p>Systems, methods, and software for implementing location-based authentication of financial transactions are provided. Upon receiving credentials to initiate a financial transaction, the geographic location and time of a device associated with the credentials are stored. When a second transaction is attempted, the geographic location and time of the second attempted transaction is determined and, based on a comparison, an implied velocity of travel between the first and second locations is calculated. If the implied velocity exceeds a velocity threshold, the second transaction may be altered or rejected. The threshold may be varied based on several factors.</p> |
